Read full description

The Magnetic Storms application was originally developed to allow monitoring of the Earth's magnetic field in near real time, using data from GOES satellites that constantly monitor solar activity and a set of magnetic stations distributed around the Earth. With the improvement of the application due to the huge number of users and the availability of new parameters related to the Sun and Space Weather by the space agencies, lots of other information was added and they are shown in a simple and intuitive way. The main parameters presented are the Kp Index, the A Index, the instantaneous speed of the solar wind, the number of class C, M and X solar flares observed in X-rays, in addition to the flux of protons and electrons, flux of X-rays and magnetic field measurements observed by GOES-16. With an analysis of this information it is possible to anticipate sudden changes in the Earth's magnetic field at ground level and the occurrence of aurora with some advance. An ideal application for anyone who wants to monitor solar activity and its implications on Earth, such as problems in the transmission of radio and TV waves, blackouts in electricity transformer stations, auroras, magnetic storms. It is the perfect app for anyone interested in Space Weather in general, and is available in English, Portuguese, Spanish, Italian and French. As a way of keeping the app distributed for free and constantly updated, we kindly ask you to rate the app ("stars") and write a brief description of why you use it and (we hope you) enjoy it. Criticism and suggestions are always welcome at mikebm10.appledeveloper@gmail.com. NOTE: the parameters shown in the application are obtained from the research entities responsible for their collection and processing, and depend on the availability and access to the electronic servers of these entities. Any connection speed problems with the servers or temporary unavailability of information by those institutions can affect the functioning of the application, and are beyond the control of the developers. Problems should be reported by email mikebm10.appledeveloper@gmail.com, with a description of the observed effects. Please do not assign a low rating in the evaluation of the application for possible failures in the servers, which are not our responsibility. An email message will be promptly answered and possible measures will be taken. We thank you for your understanding.

This app is a companion to the HamAlert web site (hamalert.org) and lets you receive push notifications from HamAlert. HamAlert is a system that allows amateur radio operators to get notifications when a desired station appears on the Reverse Beacon Network, SOTAwatch, the DX cluster or PSK Reporter. Spots can be filtered by various criteria, including: • DXCC (both actual and callsign home DXCC) • Callsign • Island reference • Summit reference • Park reference • CQ zone • Continent • Band • Mode • Time and days of week • Source • Spotter callsign and DXCC

Verdict

The call

The clearest difference is ads: HamAlert at none against Magnetic Storms's shown. HamAlert also leads on monetization model (free vs free with in-app purchases) and update cadence (every 4 months vs every 12 months). Magnetic Storms's advantage is review sentiment (82% vs 70%) and iOS requirement (12.4 vs 15.6). On price, rating, ratings volume and in-app purchases there is nothing between them.
